CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application Serial No. 62/829,217 filed on Apr. 4, 2019. The contents of the aforementioned application are incorporated by reference herein.

FIELD

The present disclosure is generally directed to bathroom and kitchen vanities and more particularly to a new, improved vanity adapted to raise and lower the height of a countertop that is attached thereto.

BACKGROUND

A conventional bathroom vanity typically has four main walls (front door frame, left side, right side and rear frame), with an open top. There may also be a bottom wall forming a storage shelf. A separate countertop with lavatory basin is supported by the vanity so that a basin drain extends into the vanity and out the vanity's rear frame. Water is typically fed to a faucet mounted through the countertop via the vanity's rear frame.

Such bathroom vanities are installed on a permanent basis and their countertops are normally of fixed height. The height of the countertop usually is determined according to industry standards in order to accommodate the average person. While standard vanities and counters are convenient for an average, ambulatory person, access is difficult for shorter individuals and those confined to a wheelchair. Accordingly, it would be advantageous to develop a vanity which can be vertically adjusted to accommodate a wide range of users.

An improved height adjustable vanity is disclosed herein. The embodiments disclosed herein are described in the context of a height adjustable vanity for use in a bathroom because the embodiments disclosed herein have particular utility in this context. However, the embodiments and inventions herein can also be applied to other types of vanities configured for other types of environments, including, but not limited to, garages, warehouses, kitchens, or any common storage areas.

With reference to FIGS. 1a and 1b , the height adjustable vanity of the present disclosure is generally represented by reference number 100. The vanity 100 can comprise a vanity structure 110 and a storage structure 120. The vanity structure 110 can rest upon or be releasably attached to the storage structure 120. The vanity structure 110 and storage structure 120 define an interior space within the height adjustable vanity 100.

According to one embodiment, the vanity structure 110 comprises a countertop. The vanity structure 110 may also comprise a sink, and in some embodiments more than one sink, such as two sinks. Thus, in one particular embodiment, the vanity structure 110 comprises a countertop 116 and a recessed sink 118. The countertop 116 and sink 118 can be formed separately and then attached together, such as for example by mechanical fasteners, adhesive, or other known fastening means. In one particular embodiment, the countertop 116 can be formed integrally with the sink 118. The sink 118 can rest within an opening formed in the countertop 116 and extends downwardly into the storage structure 120. In embodiments where there are two sinks, the countertop 116 will have two openings and each sink can rest within one opening and extend downwardly into the storage structure 120.

The countertop 116, which may be configured to be releasably attached to the storage structure 120 as further described below, can comprise a generally flat area surrounding the sink 118 and can be formed or casted from ceramic, plastic, metal, composite, laminate tile, natural stone, synthetic stone, concrete, glass sheets, agglomerated stone, cement material, terrazo or other suitable material. The flat area may be in a generally rectangular or square shape, although other shapes are possible. The countertop 116 includes a top surface 116 a and a bottom surface 116 b. The bottom surface 116 b can comprise coupling means for releasably attaching the countertop 116 to the storage structure 120 or may be a generally flat surface and rest upon the storage structure.

The sink 118 can also comprise a generally rectangular or square shape, although other shapes, sizes, and configurations of sinks are also possible, such as, but not limited to, circular and oval shapes. The sink 118 can be formed of heated ceramic material, plastic, metal, composite, or other suitable material. As noted above, in one embodiment, the sink 118 can comprise a generally recessed region. For example, the sink 118 can comprise a generally recessed region defined by a drain area 111, drain collection section 112, sloped section 113, and back wall 114. The drain area 111 can comprise a generally rounded opening within the body of the sink 118. The drain area 111 can be formed anywhere along the sink. In one embodiment, the drain area 111 can be located between the sloped section 113 of the sink 118 and back wall 114, along the drain collection section 112. In some embodiments, the drain area 111 can be located generally towards the back of the sink 118, for example, adjacent the back wall 114.

The sloped section 113 can extend from an edge of the sink 118 to the drain area 111. The sloped section 113 can have a substantially gradual slope. For example, the sloped section 113 can have a slope of approximately 10 degrees relative to the countertop 116. In some embodiments, the sloped section 113 can have a slope not greater than 10 degrees relative to the countertop 116. In some embodiments, the sloped section 113 can have a slope not greater than 15 degrees relative to the countertop 116. In other embodiments, the sloped section 113 can have a slope not greater than 20 degrees relative to the countertop 116. In further embodiments, the sloped section 113 can have a slope not greater than 25 degrees relative to the countertop 116. Other ranges of slopes are also possible. Additionally, the sloped section 113 can have a generally rectangular shape, although other shapes are also possible as well. For example, the sloped section 113 can have a trapezoidal shape, or a generally triangular shape.

With reference to FIGS. 1a, 1b and 3a , the storage structure 120 can comprise a removable upper frame structure 130 and a lower frame structure 140. The removable upper frame structure 130 and lower frame structure 140 may be made from wood and pieces of wood including natural wood, wood-based composites and combinations thereof. Such wood-based composites may include any lignocellulose fiber. For example, wood-based composites may include fiberboards, such as high density fiberboard, medium density fiberboard, oriented strand board and particle board. Natural wood can include a variety of different types of lumber such as industrial grade lumber, plywood, random length boards, clear cutstock lumber, fingerjoint cutstock lumber, ripped lumber, or other types of lumber suitable to make the wood product of interest. The type of wood is not limited to any particular species of wood. The wood may be a “hard wood,” which are typically woods from dicotyledoous trees, such as cherry, ash, mahogany, troko, beech, oak, maple, birch, walnut, teak, alder, aspen, beech, cottonwood, elm, gum, poplar or willow, or a “soft wood,” which are typically wood from coniferous trees such as larch, pine, fir, Douglas fir, hemlock, redwood, and spruce.

The removable upper frame structure 130 is configured to be releasably attached to the lower frame structure 140 and to the countertop 116 as further described below. Thus, the upper frame structure 130 may be disengaged from the countertop 116 and the lower frame structure 140 and removed from storage structure 120, thereby lowering the height of the vanity 100. Similarly, the upper frame structure 130 may be reinserted back into the storage structure 120 by disengaging the countertop 116 from the lower frame structure 140, attaching the upper frame structure 130 to the lower frame structure 140 and then attaching the countertop 116 to the upper frame structure 130, thereby raising the height of the vanity.

Coupling means can be used to releasably attach: (i) the bottom surface 116 b of the countertop 116 to the top surface 335 a of top frame 335 (and in some embodiments top surfaces 338 a of horizontal supports 338) of the removable upper frame structure 130: (ii) the bottom surface 116 b of the countertop 116 to the top surface 341 a of top frame 341 (and in some embodiments the top surfaces 344 a of horizontal supports 344) of lower frame structure 140; and (ii) the bottom surface 331 a of bottom frame 331 (and in some embodiments bottom surfaces 334 a of horizontal supports 334) of the removable upper frame structure 130 to the top surface 341 a of top frame 341 (and in some embodiments the top surfaces 344 a of horizontal supports 344) of lower frame structure 140. The coupling means may include, but is not limited to, a coupling joint. The coupling joint may be a blind joint, a dado joint, a blind dado joint, a stopped joint, a dovetail joint, a doweled joint, a blind joint, a finger joint, a half lap joint, a lock miter joint, a lock shoulder joint, a slotted mortise and tenon joint, a stub mortise and tenon joint, a through mortise and tenon joint, a rabbet joint, a scarf joint, a spline joint, a tongue and groove joint and combinations thereof.

For clarification purposes, a “butt joint” may be a joint formed by square edge surfaces (e.g., ends, edges, faces) coming together, such as an end butt joint or an edge butt joint. A “dado joint” may be a rectangular groove, typically across the grain of a wood member, into which the end of the joining member is inserted. A butt joint is also known as a housed joint, variations of which include “dado and tenon”, and “stopped or blind dado” joints. A blind or stopped dado joint is one in which the dado is not visible when the joint is completed. A “dovetail joint” may be a joint formed by inserting a projecting wedge-shaped member (i.e., a dovetail tenon) into a correspondingly shaped cut-out member (i.e., a dovetail mortise), variations of which include the “dovetail dado”, and the “blind dovetail dado”. A “dovetail, blind joint” may be a dovetail joint that is not visible when the joint is completed. A “doweled joint” may be a joint using “dowels” (i.e., doweled construction in which, typically, a wood peg or a metal screw is inserted into a hole and can be used to strengthen a wood joint); also “doweled edge joint”.

A “miter joint” typically comprises the joining of two members at an angle that bisects the angle of junction. A “lock joint miter” may be a miter joint employing a tongue and groove to further strengthen it. A “shoulder joint miter” is any type of a miter joint that presents a shoulder, such as a lock miter or a splined miter. A “blind joint mortise and tenon” is a mortise and tenon joint in which the tenon does not extend through the mortise and does not remain visible once the joint is completed, also “blind tenoned”. A “slotted joint mortise and tenon” is a mortise and tenon right angle joint in which the tenon is visible on two edges once the joint is completed. A “stub joint mortise and tenon” is a short tenon inserted in a plow or groove. A “through joint mortise and tenon” is a mortise and tenon joint in which the inserted tenon extends completely through the mortise and the end of the tenon remains visible once the joint is completed.

A “plow” is a rectangular groove or slot of three surfaces cut parallel with the grain of a wood member, in contrast to a dado, which is cut across the grain. A “rabbet joint” is a joint formed by the rabbet(s) (i.e., a rectangular cut on the edge of a member; a “rabbet” has two surfaces and a “plow” has three) on one or both members; also rabbeted edge joint; rabbeted right angle joint. A “scarf joint” is an end joint formed by having the two ends of the members beveled to form sloping plane surfaces. A “spline joint” is a joint formed by the use of a “spline”. A spline is a thin, narrow strip, usually of plywood, inserted into matching grooves which have been machined in abutting edges of panels or lumber to insure a flush alignment and secure joint. Splines customarily run the entire length of the joint. A “tenon” is a projecting tongue-like part of a wood member to be inserted into a slot (mortise) of another member to form a mortise and tenon joint. A “tongue and groove joint” is a joint formed by the insertion of the “tongue” (i.e., a projection on the edge or end of a wood member that is inserted into the groove or plow of a similar size to form a joint) of one member into the “groove” of the other.

With reference to FIGS. 5a, 5b, 5c and 5d , an example of releasably attaching the bottom frame 331 of the removable upper frame structure 130 to the top frame 341 of lower frame structure 140 using a coupling joint is depicted. In this non-limiting embodiment, bottom frame 331 can be releasably attached to top frame 341 by a coupling joint comprising a tongue and groove joint or a doweled joint or a combination thereof. The bottom surface 331 b of bottom frame 331 (and bottom surfaces 334 b of horizontal supports 334) can be placed in engagement with and attached to the top surface 341 of top frame 341 (and top surfaces 344 a of horizontal supports 344) via a tongue and groove joint to couple the bottom frame 331 and the top frame 341 together. In some embodiments, dowels, such as wooden dowels, may then be inserted into holes around bottom frame 331 (and horizontal supports 334) and top frame 341 (and horizontal supports 344) to further secure the bottom frame 331 of upper frame structure 140 and top frame 341 of lower frame structure 130 together. When it is desired to release the upper frame structure 130 from the lower frame structure 140, the dowels may be removed from the holes and the bottom frame 331 may be lifted off the top frame 341.
